The Kasta 2E radar group (NATO reporting name "Flat Face-E") is a Russian radar system, consisting of the Kasta 2E1, Kasta 2E2 and their supporting equipment. The Kasta system is designed to succeed the older Flat Face models, such as the P-15 and the P-19. Despite looking visually similar (similar radar reflectors) to the previous listed, Kasta has significant differences to the P-15 and P-19.
Development
[edit]The Kasta 2E was developed originally by the Soviet Union. Its primary objective is to overcome deficiencies or to satisfy the demand in low-level surveillance. Both radar types can be triggered with either equal or opposed phases. Both antenna types can optionally be mounted on a standard 50 meter pylon. This arrangement causes a displacement of the radar horizon which in turn increases the detection altitude up to 6 km at a distance of 150 km.
Systems
[edit]The Kasta 2E1 (51U6) system uses two antennas and consists of two vehicles:[3]
- one truck carries the antenna and its peripheral equipment
- another truck operates as command post vehicle and on a trailer unit, the external power supply is installed
The Kasta 2E2 (39N6E) system uses one antenna and consists of three vehicles:[4]
- one truck carries the antenna and its peripheral equipment
- another truck operates as command post vehicle
- a diesel-electric power plant is mounted another truck and two single-axle trailers carry auxiliary equipment
